Strada dei Boschi, 40 20852 Villasanta (MB) Italia tel. +39 039 30 2035 info@idinsertdeal.com www.idinsertdeal.com VSF3114 VSF3138 VSF3121 VSF3121/34 Stainless steel AISI 316L relief valves, suitable for compressed air, gas and liquid FEATURES Relief valve for pressure up to 50 bar (725 psi). Inlet and outlet connections 1/4 F, 3/8 F, 1/2 F and 3/4 F. Welded flange connections EN or ASME available on request. The relief valve opens when the inlet pressure increases above the set point initially regulated by the adjusting screw and it closes when the pressure goes down under the set point. Upstream pressure set point is controlled by a rubber diaphragm up to 15 bar (217 psi), by a piston for greater pressure. Available the ATEX version Brand II2GDcIICX. For use in potentially explosive atmospheres zones: 1, 21, 2, 22 (not in mines and zone 0). The product complies with the directive 97/23/CE PED.
